T85 Electrical Issue

[armitagep]

My T85 has an unpleasant quirk. Go out in the morning, 10 seconds warming the glowplugs, and she starts up immediately. Off to clean out the barn yard. If I now use the T85 for more than 10 minutes, and I then have to shut it off for some reason, it's almost a sure thing that it won't start back up. If I get out of the skid steer, then it definitely won't restart. Turning the iginition switch to start will show the usual console indicator lights, but the starter doesn't kick in. Not a peep. If I go do something else and come back 30 minutes or so later, I'll now be able to start it. I'm looking at the Safety Circuit Diagram, thinking that maybe there is a thermistor somewhere to protect against overheating (which if dodgy could have been the problem), but don't see one. Any suggestions as to what the problem might be? P.S. What is that Stop Timer-Stop Solenoid unit shown on the circuit diagram?

ARMITAGEP, I WOULD CHECK THE STARTER SOLENOID.
